If large electrical equipment is at least 6 feet wide, will a single entrance be permitted if the exit is unobstructed?

The correct answer is that a single entrance is permitted as long as it meets clearance standards. In electrical installations, safety guidelines often provide specifications that allow for flexibility based on the dimensions of the equipment and the route of egress. When large equipment exceeds a certain width, there are specific clearance requirements that must be adhered to ensure safe operation, maintenance, and emergency evacuation.

As long as the single entrance provides adequate access and complies with the necessary clearance standards—meaning it does not create a safety hazard and allows for easy movement around the equipment—it is permissible. This compliance ensures that personnel can safely operate and maintain the equipment without obstruction both during normal operations and in emergencies.

In contrast, options suggesting a double entrance or multiple exits are generally required in scenarios involving equipment exceeding the defined width if clearance or other safety considerations are not met. Thus, this approach caters to operational safety and proper safety protocol, aligning the configuration of entrances with the equipment's size and the overall safety of the environment.
